I think he meant like he’s happy he doesn’t find him annoying like he believed he did from that voice thingy back then
Then he could have said "I'm glad he doesn't hate me" cause there's a difference between being happy about someone not hating u cause u can think like "then there was nothing wrong with me" or "then I wasn't the only one who thought of us as friends" and being happy about someone telling u "I like u" while he's on top of u on a bed half naked and you have a lover... idk man it's just too weird for me. The main couple feels like they are just attracted to each other when they were supposed to be in love with each other (at least that's what I hope from... a couple?)
"I'm happy he likes me"???? Whaaat? Why are u happy my man?? And "this feels wrong" well duh of course it's wrong you have a boyfriend last time I checked (??) And the seme it's totally fine that the uke was on the bed half naked with his half naked brother and yes he could be thinking something like "he was just seeing his bruise" but then why was he hard? And WHY just WHY the seme was just casually like "oh I'll help u with that boner you got from doing something with my brother ^-^ " The lack of jealousy from the main characters toward each other and the excess from the the brother and the new guy it's so weird... The story is great don't get me wrong but I need some development cause they don't look like a couple AT ALL ┑(￣Д ￣)┍
